The much-anticipated Season 4 of Call of Duty: Mobile has finally arrived, bringing a plethora of refreshing changes to the battlegrounds. There are new content, weapons, and vehicles to enjoy. But let's not forget about the insanely broken Heartbeat Sensor COD Mobile. Read on to learn everything you need to know about how to unlock this item and how to make the most out of it in the game!

What is Heartbeat Sensor COD Mobile?

The new Season 4 of the game just dropped a few days ago. Two new weapons make their debut in Call of Duty: Mobile alongside a brand new item - the Heartbeat Sensor. If you're a big fan of the franchise, you will recognize this item immediately.

The Heartbeat Sensor has been featured in various installments of the Call of Duty series. However, the item is categorized as an attachment in Call of Duty: Modern Warfare 2, Call of Duty: Modern Warfare 3, Call of Duty Online, and Call of Duty: Modern Warfare 2 Campaign Remastered. It receives a slight change in the mobile version.

Usage of Heartbeat Sensor in COD Mobile

In Call of Duty: Mobile, the Heartbeat Sensor is a tactical item, as in Call of Duty: Modern Warfare. So, what does it do?

This tactical item allows players to track multiple targets, somewhat like the UAV killstreak. It evaluates and displays the positions or proximity of other players to the users using their heartbeat. This item will reveal enemies who are fairly close to and in front of the player.

Whenever the Heartbeat Sensor picks up a hostile target, it will introduce a beep. The beep increases in pitch the closer the target is to the user.

Unfortunately, this item is not a paywall. Call of Duty: Mobile players cannot access it in the in-game store. Instead, they have to complete various challenges to unlock this item. Read on to find out what you need to know.

Reveal the proximate location of your opponents!

This item will undoubtedly be a hot pick-up for players in the upcoming months of Season 4. Its ability to reveal the locations of enemies and the fact that it is a tactical attachment gives so many advantages.

Tips to Counter the Heartbeat Sensor COD Mobile

The Heartbeat Sensor is an insanely overpowered item in Call of Duty: Mobile. Any enemies who try to make a move will have their location immediately revealed by the sensor. In fact, the item is so broken that Activision had to take it down just a few hours after the debut.

As soon as the Heartbeat Sensor went online, a handful of players started grinding for it instantly. Once they have it, it's pretty much game over for other players. Search and Destroy matches are impossible to play if a player is using the sensor to locate players around the map.

In response, Activision had the Heartbeat Sensor COD Mobile removed a few hours after. But is this item really unstoppable? Actually, no. It has limits, but the limits are not as prominent as they are in other installments of the series.

So, what stops Heartbeat Sensor COD? Other players can shut down this tactical item by wearing a Ghost perk to hide their proximate location. EMP Drones and Stun Grenades can also disrupt the Heartbeat Sensor.

Therefore, just to be sure, we recommend bringing one of the above-mentioned items or perks to cancel out the Heartbeat Sensor, especially in Search and Destroy matches.

That's everything you need to know about the Heartbeat Sensor COD Mobile. This item is way too powerful to miss in Call of Duty: Mobile. For more information, tips, and tricks into the world of mobile gaming, visit our website at
